Almost three-quarters of riverbanks in England have no public access, according to data released by the Right to Roam campaign.

Across the country, the public cannot use riverbanks or gain access to the rivers themselves in most of the river catchments from the west of Cornwall up to the Tweed, which flows through northern England and Scotland.

Lewis Winks, an environmental social scientist from Right to Roam, who led the research, said: “Access to rivers should be a basic right, yet the vast majority remain off limits. As we continue to experience extreme heat, it’s vital the public are able to draw from the benefits that water brings.”
